Jimmy Garoppolo is going to summer school before starting training camp with the San Francisco 49ers.

Garoppolo is spending part of his down time between the end of minicamp and the start of training camp on July 27 working in Southern California with quarterback guru Tom House.

House has run a quarterback academy in Huntington Beach called 3DQB where he helps passers refine their throwing mechanics. House has worked with several star quarterbacks over the years, including Tom Brady, Drew Brees, Matt Ryan and Carson Palmer. Garoppolo has been spending time working on his mechanics all offseason as he comes back from season-ending knee surgery.

General Manager John Lynch shared a positive update on that front during an appearance on SiriusXM NFL Radio. He said Jimmy Garoppolo is throwing to his rehab partner Jerick McKinnon as the offseason gets underway.

“One of the best sights, the other day, I looked outside my office and he was throwing and throwing to Jerick McKinnon,” Lynch said.

Both players, recovering from ACL injuries, will be able to continue rehab work at the facility in hopes of being well on their way to being full participants in practice once the offseason program gets to that point, the story said.

San Francisco 49ers quarterback Jimmy Garoppolo will need season-ending surgery on his injured left knee.

The 49ers said Monday that an MRI confirmed the team's fears that Garoppolo tore his ACL while making a cut late in a loss at Kansas City. The injury deals a serious blow to the 49ers (1-2), who had planned their rebuild around Garoppolo.

Now San Francisco must go through the season with C.J. Beathard at quarterback.

He could also have MCL damage, other reports say. The Niners struggled with Beathard last season before the midseason addition of Garoppolo changed their fortunes. One bit of good news could be Carson Wentz's return from his ACL injury, which came in about 10 months. A similar time frame could potentially have Jimmy G. back late next summer. But for 2018, the rest of the offense takes a hit in the fantasy world.

The injury to 49ers quarterback Jimmy Garoppolo appears to be the worst-case scenario.

San Francisco head coach Kyle Shanahan confirmed after today’s loss to the Chiefs that the team fears Garoppolo tore his ACL.

If true, that would be a season-ending injury to the quarterback the 49ers traded a second-round draft pick to acquire and gave one of the biggest contracts to in NFL history. It's a big hit to the 49ers offense, which also lost Jerick McKinnon at RB before the season. Beathard likely takes over but is a downgrade over Garoppolo.

"WR Marquise Goodwin is clearly Jimmy Garoppolo's favorite target" and should have more touchdowns and more yards per catch, according to 49ers reporter Nick Wagoner.

Garcon will still be a factor, the story said, especially on third down. We have Goodwin ranked as our No. 30 WR, but his ADP is slightly later than Garcon's (9.04 vs. 9.01), who is our No. 43 ranked WR.

The 49ers agreed to terms on a five-year contract with Jimmy Garoppolo worth $137.5 million, NFL Network's Mike Garafolo reported, per a source informed of the decision. The deal is the largest in NFL history on an average-per-year basis.

In just seven career starts, Garoppolo has displayed unequivocally he's a franchise quarterback. Now he'll be paid like one.

Down the stretch of the season, Jimmy G elevated every player on the 49ers' roster. His pinpoint ball placement allowed previously third-fiddle receivers to morph into dangerous weapons. His quick trigger and ability to throw off his back foot aided a banged-up offensive line. His talent for moving the ball kept the 49ers' porous defense off the field and in positive situations.

In his first three games starting for the 49ers, Garoppolo led just one three-and-out punt. San Francisco scored on a whopping 62 percent of Jimmy G's drives this season -- for perspective, the Patriots were second at 51 percent.

Since he entered the NFL in 2014, Garoppolo has completed 67.3 percent of his passes (4th-highest, min. 250 attempts) with an 8.3 yards per attempt average (first) and a 99.7 passer rating (fifth).

In five starts with the 49ers (and limited weapons at receiver), Garoppolo completed 67.0% of his passes for an average of 308 yards and an 8.76 yards per attempt. He also threw six touchdowns and five interceptions in those five starts. He'll be ranked as a high-end QB2 in our early 2018 rankings.

Jimmy Garoppolo's late-season performance sends the San Francisco 49ers into the offseason with more optimism than typical for a team with a losing record.

Now the most important task of the offseason is locking up Garoppolo with a long-term deal.

"We're going to work hard to try to keep him as a 49er for a long, long time," general manager John Lynch said Tuesday. "We're really happy with the way he played. We think he's got some abilities that are unique and we want him here."

Garoppolo's arrival totally transformed a team that began the season with nine straight losses under first-year coach Kyle Shanahan and ended it with five straight wins after Garoppolo took over as starter. He threw for 1,542 yards during those starts and looked the part of a franchise quarterback the Niners (6-10) hoped they had acquired when they dealt a second-round pick to New England at the trade deadline, the story said.

There’s probably not a 3-10 team in the league feeling better about life than the 49ers.

And that’s easy to attribute to one guy in particular.

With quarterback Jimmy Garoppolo taking over two games ago and leading them to their first back-to-back road wins since 2014, the 49ers are feeling a new feeling — swagger.

“You can feel it in our building,” 49ers coach Kyle Shanahan said, via Matt Maiocco of NBC Sports Bay Area. “Guys are gaining that confidence.”

That was the goal when the 49ers made the trade for him, the story said. Garoppolo is a guy to keep an eye on the rest of this season and heading into next season, especially in Shanahan's offense. Some additional weapons in the offseason could also go a long way in increasing his fantasy value.

The Jimmy Garoppolo era in San Francisco begins in earnest on Sunday.

The 49ers announced Tuesday that the former Patriots quarterback will start against the Chicago Bears this week over incumbent C.J. Beathard.

Garoppolo threw a touchdown on his lone series against the Seattle Seahawks in Week 12.

Beathard was battling some injuries heading into this week which may have made the 49ers decision much easier. Garoppolo doesn't have a ton of weapons around him and is playing behind a bad O-line, but should have QB2 value going forward.

C.J. Beathard did not sustain a long-term injury, Kyle Shanahan said. He has a knee contusion and a hip strain. Decision by Wednesday on who will play QB for 49ers on Sunday.

With Beathard a little banged up after last week, Garoppolo would seem to have the upper hand leading up to the team's decision. We'll know the answer Wednesday.
